Follow the project:
The Riverside County Transportation Commission, in partnership with Caltrans, reconstructed the 71/91 Interchange Project in Corona.
The new 71/91 interchange opened to motorists on Monday, June 23, 2025. The new, non-tolled, two-lane direct connector replaced the existing single-lane loop connector and the newly realigned eastbound 91 Green River Rd. on-ramp now provides direct access to the new northbound 71 connector and eastbound 91 general purpose lanes.
